DX11 DX11 D3D_FEATURE_LEVEL_9_3 and Win XP

Recommended Posts

Hi All.
im trying to create a DX11 Device with D3D_FEATURE_LEVEL_9_3 under Windows XP, but it wont stat because D3D11.dll is not found.
so will this only work on Vista and Up ?
because if it does not work on XP, i guess ive got a problem for a little while, untill i get Win7 / 8.
so will i be able to develop and test a D3D11 device on D3D_FEATURE_LEVEL_9_3 under win XP ?

i just copied and pasted some of the code from the first DX11 tutorial on creating the device from the examples that come with the DX SDK.

Thanks in Advance.

DX11 does not support XP.
To support XP, you've got to use DX9.

Wait, [url="http://www.gamedev.net/topic/604914-dx11-and-building-dx9-games/page__p__4827586#entry4827586"]you've asked this before[/url]? [img]http://public.gamedev.net/public/style_emoticons/default/tongue.gif[/img]

oh, ok <_<

---edit---
i know Win XP only supports DX9, i just thought that the feature levels thing would enable me to use the DX11 API Pipeline to develop a graphics engine/framework that works across all three DX versions.
in other words, change what things are called depending on if it is Xp or Vista and up.

You can use Dx11 to run on Dx11, Dx10 or Dx9 class VIDEOCARDS. But you still need to be on Vista/7, XP isn't supported.

ja, i know that.
for some reason i just thought that it would work under Win Xp.

moderaters etc, can you please delete this thread as it contains no info.
other then me remembering DX11 supported platforms.

why was this thumbed down ?
there was (is) nothing new in this thread that anybody does not allready know.

use OpenGL to access DirectX 11 level features (OpenGL 4.x) under WinXP :D
[/quote]

thats possible ?
or does OpenGL 4.X support the same features as DX11 ?

I've never tried it, however I should be possible if you load the proper OpenGL extensions. It is worth a try. Just create an OpenGL context and check the OpenGL version.
OpenGL 4.0 (and especially 4.1) supports the same features as DX11 (as far as I know), and even more, because since then new extensions have appeared.

Yes, and yes. Except Compute Shaders - but for that you can use OpenCL.
OpenGL 4.1 core has about the same features as Direct3D11. There's even no need for extensions.

wow, thats pretty good! :cool:
so if try out OpenGL 4.X, i wont need to worry about weather certain extenstions are present ?
is OpenGL 4 only supported on new Graphics Cards, or older ones as well(3-4 years) ?

yes the opengl 4.1 core feature set contains the directx 11 feature set.
no, opengl 4 is only supported on nvidia 4xx and ati 5xxx or better. That is with a directx 10 capable video card you can't get directx 11 features (because of hardware limitations). To add directx 10 capable video cards are going to only support opengl 3.3

      SOLVED: I had written 
      Dispatch(32, 24, 0) instead of
      Dispatch(32, 24, 1)  
       
      I'm attempting to implement some basic post-processing in my "engine" and the HLSL part of the Compute Shader and such I think I've understood, however I'm at a loss at how to actually get/use it's output for rendering to the screen.
      Assume I'm doing something to a UAV in my CS:
      RWTexture2D<float4> InputOutputMap : register(u0); I want that texture to essentially "be" the backbuffer.
       
      I'm pretty certain I'm doing something wrong when I create the views (what I think I'm doing is having the backbuffer be bound as render target aswell as UAV and then using it in my CS):
       
      DXGI_SWAP_CHAIN_DESC scd; ZeroMemory(&scd, sizeof(DXGI_SWAP_CHAIN_DESC)); scd.BufferCount = 1; scd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; scd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT | DXGI_USAGE_SHADER_INPUT | DXGI_USAGE_UNORDERED_ACCESS; scd.OutputWindow = wndHandle; scd.SampleDesc.Count = 1; scd.Windowed = TRUE; HRESULT hr = D3D11CreateDeviceAndSwapChain(NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, NULL, NULL, NULL, D3D11_SDK_VERSION, &scd, &gSwapChain, &gDevice, NULL, &gDeviceContext); // get the address of the back buffer ID3D11Texture2D* pBackBuffer = nullptr; gSwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&pBackBuffer); // use the back buffer address to create the render target gDevice->CreateRenderTargetView(pBackBuffer, NULL, &gBackbufferRTV); // set the render target as the back buffer CreateDepthStencilBuffer(); gDeviceContext->OMSetRenderTargets(1, &gBackbufferRTV, depthStencilView); //UAV for compute shader D3D11_UNORDERED_ACCESS_VIEW_DESC uavd; ZeroMemory(&uavd, sizeof(uavd)); uavd.Format = DXGI_FORMAT_R8G8B8A8_UNORM; uavd.ViewDimension = D3D11_UAV_DIMENSION_TEXTURE2D; uavd.Texture2D.MipSlice = 1; gDevice->CreateUnorderedAccessView(pBackBuffer, &uavd, &gUAV); pBackBuffer->Release();  
      After I render the scene, I dispatch like this:
      gDeviceContext->OMSetRenderTargets(0, NULL, NULL); m_vShaders["cs1"]->Bind(); gDeviceContext->CSSetUnorderedAccessViews(0, 1, &gUAV, 0); gDeviceContext->Dispatch(32, 24, 0); //hard coded ID3D11UnorderedAccessView* nullview = { nullptr }; gDeviceContext->CSSetUnorderedAccessViews(0, 1, &nullview, 0); gDeviceContext->OMSetRenderTargets(1, &gBackbufferRTV, depthStencilView); gSwapChain->Present(0, 0); Worth noting is the scene is rendered as usual, but I dont get any results from the CS (simple gaussian blur)
      I'm sure it's something fairly basic I'm doing wrong, perhaps my understanding of render targets / views / what have you is just completely wrong and my approach just makes no sense.

      If someone with more experience could point me in the right direction I would really appreciate it!

      On a side note, I'd really like to learn more about this kind of stuff. I can really see the potential of the CS aswell as rendering to textures and using them for whatever in the engine so I would love it if you know some good resources I can read about this!

      Thank you <3
       
      P.S I excluded the .hlsl since I cant imagine that being the issue, but if you think you need it to help me just ask

      P:P:S. As you can see this is my first post however I do have another account, but I can't log in with it because gamedev.net just keeps asking me to accept terms and then logs me out when I do over and over

      Does buffer number matter in ID3D11DeviceContext::PSSetConstantBuffers()? I added 5 or six constant buffers to my framework, and later realized I had set the buffer number parameter to either 0 or 1 in all of them - but they still all worked! Curious why that is, and should they be set up to correspond to the number of constant buffers?
      Similarly, inside the buffer structs used to pass info into the hlsl shader, I added padding inside the c++ struct to make a struct containing a float3 be 16 bytes, but in the declaration of the same struct inside the hlsl shader file, it was missing the padding value - and it still worked! Do they need to be consistent or not? Thanks.
          struct CameraBufferType
          {
              XMFLOAT3 cameraPosition;
              float padding;
          };

      I was wondering if anyone could explain the depth buffer and the depth stencil state comparison function to me as I'm a little confused
      So I have set up a depth stencil state where the DepthFunc is set to D3D11_COMPARISON_LESS, but what am I actually comparing here? What is actually written to the buffer, the pixel that should show up in the front?
      I have these 2 quad faces, a Red Face and a Blue Face. The Blue Face is further away from the Viewer with a Z index value of -100.0f. Where the Red Face is close to the Viewer with a Z index value of 0.0f.
      When DepthFunc is set to D3D11_COMPARISON_LESS the Red Face shows up in front of the Blue Face like it should based on the Z index values. BUT if I change the DepthFunc to D3D11_COMPARISON_LESS_EQUAL the Blue Face shows in front of the Red Face. Which does not make sense to me, I would think that when the function is set to D3D11_COMPARISON_LESS_EQUAL the Red Face would still show up in front of the Blue Face as the Z index for the Red Face is still closer to the viewer
      Am I thinking of this comparison function all wrong?
      Vertex data just in case
      //Vertex date that make up the 2 faces Vertex verts[] = { //Red face Vertex(Vector4(0.0f, 0.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), Vertex(Vector4(100.0f, 100.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), Vertex(Vector4(100.0f, 0.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), Vertex(Vector4(0.0f, 0.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), Vertex(Vector4(0.0f, 100.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), Vertex(Vector4(100.0f, 100.0f, 0.0f), Color(1.0f, 0.0f, 0.0f)), //Blue face Vertex(Vector4(0.0f, 0.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), Vertex(Vector4(100.0f, 100.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), Vertex(Vector4(100.0f, 0.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), Vertex(Vector4(0.0f, 0.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), Vertex(Vector4(0.0f, 100.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), Vertex(Vector4(100.0f, 100.0f, -100.0f), Color(0.0f, 0.0f, 1.0f)), };

      Hi all,
      First time poster here, although I've been reading posts here for quite a while. This place has been invaluable for learning graphics programming -- thanks for a great resource!
      Right now, I'm working on a graphics abstraction layer for .NET which supports D3D11, Vulkan, and OpenGL at the moment. I have implemented most of my planned features already, and things are working well. Some remaining features that I am planning are Compute Shaders, and some flavor of read-write shader resources. At the moment, my shaders can just get simple read-only access to a uniform (or constant) buffer, a texture, or a sampler. Unfortunately, I'm having a tough time grasping the distinctions between all of the different kinds of read-write resources that are available. In D3D alone, there seem to be 5 or 6 different kinds of resources with similar but different characteristics. On top of that, I get the impression that some of them are more or less "obsoleted" by the newer kinds, and don't have much of a place in modern code. There seem to be a few pivots:
      The data source/destination (buffer or texture) Read-write or read-only Structured or unstructured (?) Ordered vs unordered (?) These are just my observations based on a lot of MSDN and OpenGL doc reading. For my library, I'm not interested in exposing every possibility to the user -- just trying to find a good "middle-ground" that can be represented cleanly across API's which is good enough for common scenarios.
      Can anyone give a sort of "overview" of the different options, and perhaps compare/contrast the concepts between Direct3D, OpenGL, and Vulkan? I'd also be very interested in hearing how other folks have abstracted these concepts in their libraries.

      If I do a buffer update with MAP_NO_OVERWRITE or MAP_DISCARD, can I just write to the buffer after I called Unmap() on the buffer? It seems to work fine for me (Nvidia driver), but is it actually legal to do so? I have a graphics device wrapper and I don't want to expose Map/Unmap, but just have a function like void* AllocateFromRingBuffer(GPUBuffer* buffer, uint size, uint& offset); This function would just call Map on the buffer, then Unmap immediately and then return the address of the buffer. It usually does a MAP_NO_OVERWRITE, but sometimes it is a WRITE_DISCARD (when the buffer wraps around). Previously I have been using it so that the function expected the data upfront and would copy to the buffer between Map/Unmap, but now I want to extend functionality of it so that it would just return an address to write to.
